[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 2 In this embodiment, a ceramic thermal insulation pad with variable size includes a pad body 1, an inner cavity of the pad body 1 is provided with two deployable movable pads 2, a transmission component 3 for transmitting power is provided in the inner cavity of the pad body 1 and between the two movable pads 2, and two limiters 4 for limiting the movable pads 2 are provided on the left and right side walls of the pad body 1.

[0024] In addition, a rotating hole is provided on the right inner wall of the inner cavity of the pad body 1, and a stabilizing hole is provided on the right outer wall of the pad body 1. The stabilizing hole is connected to the rotating hole. The radius of the stabilizing hole is larger than that of the rotating hole. The stabilizing hole is used to clamp the knob 3033. The setting of a rotating hole with a smaller radius can ensure the smooth rotation of the active rod 301. Each movable pad 2 includes a movable block 201 movably connected to the inner cavity of the pad body 1, and a tooth plate 202 is fixed on the opposite side of the two movable blocks 201.

[0025] In this embodiment, the space utilization rate in the pad body 1 can be effectively improved by alternately arranging the tooth plates 202, thereby ensuring the maximum stretching area in a limited space. At the same time, in conjunction with the transmission component 3, efficient power transmission can be achieved, thereby improving the use efficiency of the ceramic insulation pad.

[0026] Please refer again Figure 1 and 3 In order to smoothly transmit power, the transmission assembly 3 in this embodiment includes an active rod 301 rotatably connected to the left side wall of the inner cavity of the pad body 1 through a bearing. Three active gears 302 are fixed to the outer surface of the active rod 301. The provision of three active gears 302 can improve the stability of the moving pad 2, make the moving pad 2 more evenly subjected to force, and improve the smoothness of the movement of the moving pad 2. A rotating part 303 is provided on the right side of the active rod 301.

[0027] In addition, the active rod 301 passes through the stabilizing hole and extends into the rotating hole. A snap-fit hole is provided at the right end of the active rod 301, and a snap-fit tooth is fixed in the snap-fit hole. The active rod 301 is engaged with the cylindrical gear 3031 through the snap-fit tooth. The snap-fit tooth in the active rod 301 and the cylindrical gear 3031 cooperate with each other to ensure that power can still be transmitted to the active rod 301 when the rotating part 303 moves.

[0028] It can be seen that a plurality of long teeth are fixed on the opposite side of the two tooth plates 202. The two tooth plates 202 are meshed with the three active gears 302 through the plurality of long teeth. The rotating part 303 includes a cylindrical gear 3031 that is clamped with the right end of the active rod 301. A knob 3033 is fixed to the right end of the cylindrical gear 3031. A compression spring 3032 is fixed between the knob 3033 and the active rod 301. The provision of the compression spring 3032 can ensure that when the end cover 3034 is removed, the knob 3033 pops out smoothly, which is convenient for the user to perform subsequent operations. The compression spring 3032 is located at the cylindrical gear The outside of 3031 is coaxial with the cylindrical gear 3031, and the right side of the pad body 1 is threadedly connected to the end cover 3034. A plurality of clamping blocks are fixed in the stabilizing hole, and the clamping blocks can limit the knob 3033. When the knob 3033 is used, when the knob 3033 is pressed into the pad body 1, the clamping block can prevent the end cover 3034 from rotating accidentally, which can effectively improve the stability of the device. A plurality of friction blocks are fixed on the outer surface of the knob 3033, and the plurality of clamping blocks are adapted to the plurality of friction blocks. The left and right side walls of the pad body 1 are fixed with threaded connection blocks, and the right side threaded connection block is threadedly connected to the end cover 3034.

[0029] It should be further explained that two limiting holes are provided on the left and right side walls of the inner cavity of the pad body 1, and limiting grooves are provided on the left and right sides of each moving block 201. Each limiter 4 includes a limiting spring fixed to the inner bottom wall of the limiting hole. The limiting block is fixed at one end of the limiting spring close to the moving block 201, and the limiting block is adapted to the limiting groove. Through the cooperation of the limiting groove and the limiter 4, the two moving pads 2 can be effectively limited, further ensuring the stability of the two moving pads 2.

[0030] In this embodiment, the compression spring 3032 can cause the knob 3033 to pop out quickly, thereby improving the response speed of the knob 3033 and facilitating user operation. At the same time, the limiter 4 can effectively improve the stability of the moving pad 2.

[0031] It can be understood that by cooperating with the movable pad 2 and the transmission assembly 3, the size of the ceramic thermal insulation pad can be adjusted, and the cooperation with the limiter 4 can increase the service life of the movable pad 2. At the same time, the special shape of the limit block and the limit groove can ensure that the movable pad 2 will not be stuck by the limiter 4 when returning to its original position.

[0032] The working principle of the above embodiment is:

[0033] When the container is small, the container can be placed directly on the front of the cushion body 1 to achieve a heat insulation effect. When the container is relatively large, the knob 3033 is twisted off and twisted to the left threaded connection block. At this time, under the action of the compression spring 3032, the knob 3033 on the rotating part 303 will pop out. The user can directly twist the knob 3033, and the power will be transmitted to the three driving gears 302 through the active rod 301, and the three driving gears 302 will rotate simultaneously. When the driving gears 302 rotate, Drive the two tooth plates 202, and further drive the two moving blocks 201 to move outward, so as to adjust the size of the ceramic insulation pad. After the adjustment is completed, press the knob 3033 into the pad body 1, and re-fix the end cover 3034 to the right threaded connection block. In order to prevent the two moving pads 2 from being completely separated from the pad body 1, the limiter 4 and the limit groove cooperate to achieve a good effect. The ceramic insulation pad can adapt to containers of different sizes by adjusting its own size, ensuring the thermal insulation effect and providing sufficient protection for the desktop.
